The seven questions facing Martin O’Neill and Celtic heading into a three-week break

Celtic manager Martin O'Neill faces significant pressure and questions about his future during a three-week international break following a series of poor results. The Scottish Premiership club recently suffered a defeat against rivals Rangers, which has intensified scrutiny on the manager's tactical decisions and squad selection.

Key issues facing the team include determining the best tactical formation after unsuccessful experiments with a back three and a 4-4-2 system. Additionally, O'Neill must resolve selection dilemmas regarding the starting goalkeeper position between Viljami Sinisalo and Sam Johnstone, as well as finding the right defensive partnership alongside Cameron Carter-Vickers.
